All I can do after that is look for visual evidence of any penetration into the metal. I am able to take pretty thick slices of the iron, and I intend to do that.
This won't be a published, peer-reviewed experiment under lab conditions. So, it won't satisfy everyone, but I'm really doing it to satisfy myself. This is the first time I've ever bought Zmax, and if I'm convinced that it's worthless, it will be the last.
I also drilled a shallow hole in a piece of 3/16" mild steel to see if it would penetrate the steel at all. I've heated it and let it cool a couple of times, and while it did travel across the surface during this time, so far I see no sign of absorption. I believe Maurice LaPera did use the word "absorb" in the paper published on the Zmax website.
Can you borrow a X1000 mircroscope from someone close by?
If I can, I will. If you want me to send you any of the pieces, I can do that, too.
Clevy, I'll post pics and results on BITOG. I don't know what the results will be. I'm going to do a number of hot-cold cycles, and leave plenty of dwell time to give the Zmax the best benefit of the doubt. So it will be at least a few days before I'm ready to start cutting (and hopefully drawing conclusions).
It's already clear that Zmax really attacks rust. I put a teensy amount on some rusted angle iron, and brushed it with a wire brush about a day later. The area that the Zmax had penetrated (I don't think anyone is disputing that light oils will penetrate rust) brushed off much more easily than adjacent areas. That doesn't necessarily mean much by itself - motor oils have anti-rust and anti-corrosion properties as well. Just an observation, and I think it supports one of Zmax's claims.
